No status for that one. 
What's the default duration for a US patent ?
From the first page description (which is all I can read), it seems
to patent an idea as well as an apparatus.
I have no apparatus and patent on idea are not applicable in my country.
 (Moreover, computer program are not protected by patent here, but by 
 author's right)
At most, 2 of the 6 methods for tesselation in my code might be subject
 to importation-in-US-restriction, the same two that I do not write the arrays
 myself (the code is mine 100%, but I copy some data arrays from a web page).
So far, I would have to check the nationality and clearance of Heller and Bourke,
the two people which provide the data arrays.

That one is Expired. <Plonk>

Side note: maybe it's time to enforce an importation-banning rule for the US!
Just like the US have an exportation-banning rule regarding crypto and other things!
